Do you use a bank? Do you shop at a store? Post a letter? Even people who don't have or use computers are dependent on cloud computing. All of us use services available in our societies, and those services may depend upon cloud computing, or rely upon service providers who depend upon such services.
VMs have been part of computing since 1972, and operational factors have been a consideration ever since. But focus and attention have mainly been on resource management, performance, and operational stability, not on security.
